Abstract:
A method for wireless communication combines OFDMA resource allocation and power control policies with cooperative relaying techniques. The techniques are preferably implemented in a dense wireless network of power-limited mobile devices assisted by mobile relay devices having superior power supplies. Preferably, MIMO beamforming techniques are used to further increase energy efficiency and spectral efficiency beyond the increases provided by ODFMA cooperative relaying.
